4 1. General description The regulators are designed for online measurement of temperature ( C or F), relative humidity and carbon dioxide concentration of air. Measured temperature and relative humidity are recomputed to following humidity expression: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy. The regulators are designed to be operated in a chemically non-aggressive environment. 104DE DE - - Type Temperature Humidity CO 2 Computed value AT-VLS- AT-VLS- AT-VLS- 102DE AT-VLS- 106DE The device is equipped with two relay outputs for alarming or controlling of external devices. It is possible to assign any input value to each relay, to set comparing limit, delay, hysteresis and acoustic alarm or change its status by far control with using of Modbus communication protocol. The device is communicating through Ethernet interface. The device is internally separated into two units. The first unit provides measurement and controlling of output relays there is possible to change these parameters directly through device s keys or TSensor software. The second unit provides all Ethernet services, its configuration is possible through Telnet terminal or TSensor software (this setting is impossible to change through device s keys). Measured and calculated values are available from Ethernet interface or are displayed on LCD. If there are two values displayed at one LCD line, they are periodically switched between both readings with period of 4 seconds. Display can be switched OFF totally. On the left LCD side there are placed three LEDs for CO 2 zone level indication. The following formats are supported: WWW pages with user-design possibility Modbus protocol SNMPv1 protocol SOAP The instrument may send a warning message to several defined points if the measured value gets out of adjusted limits. There are the following possible ways to deliver the warning report: to send an to maximum of three addresses to send a SNMP trap to maximum of three IP addresses to display an alarm state on the device WWW page to send a message to Syslog server Alarm limits may be set via TSensor software, Modbus, Telnet or a SNMPv1 protocol. The alarm state may be read via the device WWW pages, Modbus or the SNMPv1 protocol. The value assign to each relay is possible through TSensor software or through device s keys. If Power over Ethernet is needed, it is necessary to use some PoE Splitter. Tested is e.g. D-Link DWL- P50. Regulator itself does NOT support PoE internally! Regulator supports Internet protocol version 4 (IPv6 is NOT supported)

5 2. Regulator mounting and connection Regulators are designed for wall mounting. Device must be mounted on the plane surface to prevent its deformation. Mounting holes and connection terminals are accessible after demounting of four screws in the corners of the box and removing the lid. There is recommended to use screws with half round head with cross-recessed screw ST 3.9 (DIN 7981). External probe for measuring the concentration of CO2 unpack and connect to the device. Lace the lead-in cable with outer diameter of 3 to 6.5 mm through the glands at the case wall and connect them according schematic below. Terminals are selfclamping and can be opened by a suitable screwdriver. For the opening, insert the screwdriver to smaller terminal hole and lever by him. Do not forget to tighten glands and case lid with inserted packing after cables connecting. Insert attached plug into unused cable glands too. Do not connect the regulator under voltage. It is not recommended to use the device AT-VLS- 102DE and external RH+T probe of AT-VLS-106DE regulator for long time under condensation conditions. It could be the cause of water steam condensation inside the sensor s cover into water phase. This liquid phase stays inside sensor s cover and can t escape from the cover easily. It can dramatically increase response time to relative humidity change. If water condensation occurs for longer time it can cause sensor damage. Similar effect can occur under water aerosol conditions. The communication cable must be placed as far as possible from potential interference sources. Electrical system (wiring) may be done only by a worker with required qualification by rules in operation. 3. Preparation to operation To provide all Hx5xx regulator functions it is necessary to make its setting through PC to satisfy your requirements. Requested parts necessary for operation: ac/dc adapter 9-30V, 200mA or PoE splitter RJ-45 LAN connection free IP address in your network Contact network administrator to get free IP address. Warning! Reliability of warning messages reception ( , trap) depends on current accessibility of required network services. It is recommended to protect device from unauthorized access to device settings and cables connection. 5

10 5. Installation It is necessary to assign a new suitable IP address to the device at the first connection to it in order to prevent collisions with already existing network IP addresses, and make the address conform to the local habits. If installing several new devices, connect them to the network one after another! If a suitable IP address is not known, contact your network administrator and ask him for the following: IP address of regulator IP address of gateway Network mask The IP gate address and the network mask need not be specified if the device will be operated only in a local network. If you set the IP address to one which is already used in the network the device will NOT work correctly and collisions in the network will appear. It is possible to set the IP address by DHCP server. Device setting from the manufacturer: IP address: Gateway: not set Value assigned to Relay1 and Relay2: none Password for setting through keys (PASS): 0000 Password for setting via TSensor: none Value shown at first LCD line: temperature / CO2 - by device type Value shown at second LCD line: relative humidity / dew point temp. - by device type Temperature unit: C Computed value preset: dew point temperature Relay response for error: stay unchanged at previous condition Acoustic alarm: off LED indication of CO 2 concentration: up to 1000 ppm lights green LED, between 1000 and 1200 ppm lights yellow LED and over 1200 ppm lights red LED altitude: 300 m above see level at the installation site 5.1. Installation procedure run TSensor software (default regulator IP address is ) or use command line at PC with command telnet Telnet provides to set all Ethernet services. For setting of measurement and controlling of output relays use keys see chapter Regulator setting change part of measurement unit at page 13. assign new regulator IP address make your own regulator setting by your requirements (alarm settings, used units, and trap sending...) and save settings 6. Operation checking 6.1. Visual check When power source is on, there are actually measured values shown on LCD (if the LCD has not been switched off). When Ethernet cable is connected, there is one light on its connector lighting. 10

11 6.2. Communication check via a LAN Open a browser of WWW pages and enter the devices IP address into appropriate field. Example: Regulator shows its name, serial number, measured values, alarm status and alarm settings or shows message Access denied in case of web pages are disabled or setting through Telnet is in operation. 7. Description of device function and setting Information from regulator is available directly through LCD or you can read them with one of next communication protocols. For communication through some communication protocol (SNMPv1, Modbus, SOAP) there is necessary to have installed appropriate software supporting appropriate communication protocol on PC. Such software is not included in the delivery! The device is internally separated into two units. The first unit provides measurement and controlling of output relays these parameters are possible to change directly through device s keys or TSensor software. The second unit provides all Ethernet services, its configuration is possible through Telnet terminal or TSensor software (this setting is impossible to change through device s keys) Relay outputs Regulator is equipped with two relay outputs. It is possible to assign any input or computed value or far control to each relay, to set comparing alarm limit, if the relay may close if measured value is higher (Hi) or lower (Lo) than preset limit, delay for while must be preset condition true before relay close its contact and hysteresis for return to open status. Each relay status is indicated with LED diode and shown on LCD with corresponding symbols or. The output relays of device are not able to switch power circuits or higher voltages. In such case we should use suitable type of power relays with coil in accordance to chapter Common parameters. For wiring see Appendix A Carbon dioxide concentration measurement Principle of CO 2 concentration measurement is based on Non-Dispersive Infrared Technology (NDIR). It is maintenance free because of the patented auto calibration feature, compensating for the effects of aging and therefore a guarantee for outstanding long-term stability. If the device is in operation permanently, an auto-adjustment will start automatically after 24 hours operation each. Measured values can be read in SLOW mode (filtered, averaged) or in FAST mode (current values without averaging). SLOW mode has advantages in applications like climate control because of filtering short time peaks. As an example exhaled air from an employee passing the sensor could affect the climate control negatively with a short response time because the control would trigger a change of the ventilation based on this onetime measurement. On the contrary in FAST mode no software filter is used for calculating the output value. This fact adds a noise of typ. ±30ppm which has to be considered in terms of accuracy. Of principle measurement is the measured value of CO 2 concentration depends on the value of air pressure - altitude at the installation site. For this reason, it is suitable for accurate measurement to set the altitude of the installation site by TSensor software. After power up there is internal check in progress and takes about 20 s. During this time LCD display shows (----) instead of CO 2 concentration value. Parameter setting description is into chapter Regulator setting change part of measurement unit at page

12 7.3. Actual regulator preset measurement part It is NOT possible to make any changes of Ethernet services, for their setting see chapter Regulator configuration Ethernet interface at page 19. If output relay alarm condition configuration is made using Modbus protocol, keyboard is blocked for this time. During this configuration is a word bloc shown in the display. It is possible to display actual regulator preset on its LCD display by pressing of key. LCD shows information about Relay1 and then Relay2 setting step by step. Information about Relay1 are indicated with symbol, for Relay2 with symbol (at right top corner of LCD). It is possible to edit parameters after pressing SET key and entering of correct password PASS - see chapter Change of Password for setting through keys (PASS) at page 16. Following examples are for Relay1 setting, similarly are displayed values for Relay2. Pressing of ESC key ends this mode and switch to actual value displaying, the same occur if more than 20 s is not pressed any key Value assigned to output relay None, relay is still off Temperature at C Relative humidity Computed value dew point temperature CO 2 concentration Far condition 0 Far condition 1 FAR0 far condition 0 : after device s power on the relay is open FAR1 far condition 1 : after device s power on the relay is close If far condition is assigned to output relay, then there is possible to change the output relay status by Modbus communication protocol only. See chapter Modbus protocol at page When close output relay High limit HI the relay close when measured value exceeds preset high limit for longer time than preset delay time. Relay goes open when measured value decrease under high limit value minus the hysteresis value. See example. 12

13 High limit HI Delay [s] Hysteresis Low limit Lo the relay close when measured value falls below preset low limit for longer time than preset delay time. Relay goes open when measured value exceeds low limit value plus the hysteresis value. See example. Low limit Lo Delay [s] Hysteresis 7.4. Regulator setting change part of measurement unit Setting with PC and TSensor software User s software TSensor is available free to download at web page. It provides setting of all regulator parameters. Run the TSensor program and follow the program instructions. Regulator includes hardware write protection of internal setting (except of Ethernet setting which is protected by password), new setting is possible to write only while: 13

14 1. during write period press SET key do requested setting in TSensor software, press SET key on regulator and keep it down, then click on the button Save Changes into TSensor software and after end of write release SET key, or 2. jumper placed nearby keys is closed (jumper is accessible after demounting of four screws in the corners of the box and removing the lid, don t confuse with jumper nearby Ethernet connector!). This jumper is suitable e.g. until device adjustment is in process and regulator is placed into calibration box and keys are not accessible. Don t forget to remove (open) jumper after procedure finish (restore write protection) TSensor software supports to make the adjustment of the regulator too. This procedure is described at file Calibration manual.pdf which is installed commonly with the software Setting with using regulator keys If Actual regulator preset is displayed, it is possible to enter into edit mode and edit displayed value by pressing SET key. Then you are asked for valid password PASS. You can edit selected value if right password is entered. During value editing there is range check executed and edited value is still compared with limits for corresponding value (range). If inserted value is higher or lower then edited number is automatically changed to its maximum / minimum value for possible range see chapter Technical parameters at page 26. Value can be changed with using and keys. Edited value is switched in round -9, -8, -7, -2, -1, 0, 1, 2, 8, 9. To edit next number digit press SET key, for moving back to previous digit press ESC key. Edited value is stored by next SET key pressing. It is possible to cancel editing by pressing ESC key if necessary. If valid password is once inserted right, then there is possible to edit next items without asking for password insertion again, till Actual regulator preset is left (till actual measured values are shown). With new entering into edit mode it is necessary to enter Password again. Default password setting is preset from manufacturer to 0000, password change is possible into Extended setting. During edit mode regulator still works and changes are valid immediately after its storing it is not necessary to restart regulator Extended setting mode During regulator operation it is possible to change parameters available through Actual regulator preset only (see chapter Actual regulator preset measurement part at page 12). Rest of regulator parameters are available through Extended setting mode. In this mode regulator does NOT communicate, does NOT do any measurements and does NOT service output relays. To leave this mode press ESC key and open jumper nearby keys. To enter into extended setting mode do following steps: 1. disconnect power supply 2. demount four screws in the corners of the box and remove the lid 3. closed jumper placed nearby keys (don t confuse with jumper nearby Ethernet connector 4. press and keys together and keep them down 5. connect power supply to regulator you should see message SEL on the top line of LCD and on the bottom line you should see number of Firmware version (e.g. 0401) 6. release and keys you are into Extended setting mode now Use and keys to inspect each items. If you want to change some shown item then press SET key, item starts blink. Now you can edit setting with using and keys. To store preset value press SET key. Press ESC key to leave editing (changing) without save last stored value is kept. 14

In case error of assigned value measurement is found then output relay: stays unchanged (in previous status) Relay1 switch OFF Relay1 switch On stays unchanged (in previous status) Relay2 switch OFF Relay2 switch On password setting 15

16 Change of Password for setting through keys (PASS) This item shows actual password setting. It is possible to change it after SET key pressing. It is number from range to Temperature unit choice It is possible to measure temperature at C or F. There is shown preset unit. It is possible to change it after SET key pressing. preset to C preset to F CO 2 measurement mode selection This item provides to choice if measured value is displayed and read in SLOW or FAST mode. FAST mode provides last measured value without averaging; this means that no software filter is used for calculating the output value. SLOW mode provides value averaged from last 11 FAST measured values. averaged value SLOW mode current value without averaging FAST mode CO 2 zone level indication setup Whole measuring range can be divided into three areas. Each active area there is indicated by green, yellow or red LED depends on actual measured value. It is done by two boundary limits setting. YELL limit sets boundary between green and yellow indication. It means that if actual measured value is lower than YELL limit, there is green LED active. If actual measured value is higher than YELL limit, then there is yellow LED active. Yellow LED lights until actual measured value exceeds RED limit. If actual value is higher than RED limit, red LED is active. If you don t want to use this indication then set YELL limit to 0. YELLOW limit setting RED limit setting 16

It is possible to change it after SET key pressing. show value on LCD don t show value on LCD Show relative humidity at LCD display This item provides to choice if actual measured relative humidity may be displayed at LCD display or not. It is possible to change it after SET key pressing. show value on LCD don t show value on LCD Show computed value at LCD display This item provides to choice if actual computed value may be displayed at LCD display or not. There is shown the name of computed value on the top LCD line. It is possible to change it after SET key pressing. show value on LCD don t show value on LCD Show CO 2 concentration at LCD display This item provides to choice if CO 2 value may be displayed at LCD display or not. It is possible to change it after SET key pressing. show value on LCD don t show value on LCD 17

18 Computed value selection It shows the actually selected computed value name. It is possible to change it after SET key pressing. There is possible choice one of the following computed values: dew point temperature absolute humidity mixing ratio specific humidity specific enthalpy 7.5. Restore to Factory default measurement part This item provides regulator restoring to factory setting. Press SET key, select YES and confirm it by pressing of SET key. It reset regulator parameters to following values: Value assigned to Relay1 and Relay2: none Password for setting through keys (PASS): 0000 Display: on Temperature unit: C Computed value preset: dew point temperature Relay response for error: stay unchanged at previous condition Acoustic alarm: off restore to factory default 18

19 7.6. Regulator configuration Ethernet interface The Ethernet configuration is performed by TSensor software 1 or Telnet setup. Setting through the Telnet is described in separated document. Access to the Setup can be protected by a password. TSensor program you can find on web or on the installation CD. This program is free for use and supports firmware update. The newest firmware is available at web pages too Alarms Ethernet interface Analogue values It is possible to set an upper limit, lower limit, hysteresis and time delay to each measured value. Figure shows a temperature curve with some specified upper limit (temp_limit_high) and hysteresis. At point 1 temperature exceeds the limit. From that moment a time delay is counted (time_delay) after which an alarm is set. Because at point 2 the temperature dropped below the limit value (temp_limit_high) before the time delay expired, alarm was not set. At point 3 the temperature again exceeded the limit, and because it did not drop below the limit value (temp_limit_high) before the time delay ended, the alarm was set at point 4. At this moment the alarm s and traps are sent, if they are enabled, and the alarm flag is set (the flag is set when the alarm is active and reset when inactive). The state of the flag can be found on the WWW pages or via Modbus or the information console. The alarm lasted to point 5, where the temperature dropped below the limit value given by the adjusted hysteresis (hysteresis). For other measured values the principle of alarm activity is analogical. An alarm report is always sent right after an alarm appears. The device memorizes sent alarm reports of current alarms while the power is connected. In case of power disconnection or a reset of the device (e.g. by modification of configuration) a new alarm evaluation is performed and new alarm reports are sent again, if any. It is possible to set the alarm parameters via telnet, Modbus protocol or a SNMPv1 protocol, TSensor program. Detailed description of setting via these protocols can be found in chapters informing about particular services. 1 In telnet some settings are not allowed (display settings, computed value selection), see chapter

Factory default Ethernet interface This procedure describe how set Ethernet interface of device to factory defaults (new IP address: , mask: ). 1. power off device 2. remove device cover 3. close jumper near the Ethernet interface 4. power on the device 5. wait approximately 15s 6. open jumper (remove shorting link) 7. close device cover 8. Communication protocols 8.1. Modbus protocol The device contains support for the Modbus TCP protocol to communicate with control systems. The port is set to 502. Port 502 enables full access, i.e. both read and write operations are supported. Access to port can be disabled in the Setup. Maximal number of client transaction is set to 1. Supported Modbus commands: Command Code Description Read multiple register(s) 0x03 Reads 16 bit register(s) Write multiple register(s) 0x10 Writes 16 bit register(s) Modbus registers of regulator: Variable Unit Format Address Address [hex] [dec] Status measured temperature C, F Int*10 0x r measured relative humidity (RH) % Int*10 0x r computed value (CV) CV depend Int*10 0x r CO 2 concentration displayed on LCD ppm Int 0x r device serial number Hi - BCD 0x r device serial number Lo - BCD 0x r Relay1 status [0/1] - Int 0x003B 59 r Relay2 status [0/1] - Int 0x003C 60 r far Relay1 control (see below) - Int 0x r/w [0 relay open, 1 relay closed] far Relay2 control (see below) - Int 0x r/w [0 relay open, 1 relay closed] CO 2 concentration FAST mode value ppm Int 0x r CO 2 concentration SLOW mode value ppm Int 0x r status word (described below) - Int 0x r firmware version Hi - BCD 0x r firmware version Lo - BCD 0x r lower limit for temperature C, F Int*10 0x r/w upper limit for temperature C, F Int*10 0x r/w 20

22 8.2. SMTP In case of exceeding adjusted limits of measured values the device can send s to maximum of three addresses. It is necessary to set your SMTP server address (IP address, authentication, etc.) for correct function of sending. If limits of several measured values are exceeded a special alarm is sent for each alarm state. Dummy address sensor@[device IP address] is displayed as a sender of the . It is not possible to reply to this address. In the Subject field of the message the sentence Alarm [Description of the device] is displayed or Test message [Description of the device] in the case of sending a test SNMPv1 By means of the SNMPv1 protocol it is possible to find currently measured values, read and set parameters concerning alarms. In case of alarm activation, warning message (a trap) can be sent to specified addresses. By means of the SNMPv1 protocol it is also possible to display history of last 100 measured values. For read and write the device communicates via UDP port 161. Traps are sent via port UDP port 162. Sending of traps can be disabled in the Setup. The following traps sent 0/0 device restart 1/0 testing trap 1/1 SNTP time synchronization error 1/2 Ethernet firmware was uploaded 1/3 1/5 SOAP communication error 1/6 1/8 sending error 1/9 Configuration changed via SNMP or Modbus 6/3 6/55 report on a measured value being outside of the limits or a return of the measured value to the limits For the correct function of the SNMPv1 server it is necessary to store the MIB table Hx5xx.mib and RFC-1213.mib to the MIB client. The path to the device is then: iso.org.dod.internet.private.enterprises.comet.products.hx5xx MIB tables are available on the installation CD in the MIB directory. Password for a read operation is set by the manufacturer to public, password for write is set to private. These passwords may be changed in the setup. History By means of the SNMPv1 protocol it is possible to display history of the last 100 measured values, stored in adjusted time interval. This interval is set by configuration program. If a value has not been measured yet or an error was detected the value is 9999, or -9999, if pressure is measured. The history is erased after each restart of the device. Restart occurred if device configuration is changed via keyboard or TSensor software. 22

23 8.4. WWW The device supports display of measured values, adjusted limits and alarm states on its WWW pages. The address of the WWW pages is identical with its IP address. It is possible to upload self-made web pages to device. Example: The device has an IP address Enter to the browser address field and confirm it with the Enter key. WWW pages have adjustable automatic refresh interval. The manufacturer sets it to 60 seconds. The value can be modified in the setup in a range of s. If the device has WWW pages display disabled screen with message Access denied SNTP The device allows time synchronization with SNTP server. The time synchronization is set to every 8 hours. If the time synchronization failed in next three hours, SNTP trap, and Syslog message will be sent Syslog protocol Device allows send messages to selected Syslog server (UDP protocol, port 514). Events are described below. Event device restart test message alarm occurred SNTP connection error write to device via Modbus, SNMP firmware was changed alarm is down SOAP server communication error sending error Text Device restart Testing message Alarm NTP connection error Settings changed Firmware uploaded Clearing SOAP SOAP Device allows sending SOAP messages with measured values to user defined remote web server in preset time intervals s. If the device cannot establish connection with the web server in the whole delay interval, device sends trap 1/3 1/5. How to configure sending SOAP messages example: SOAP enable: Yes Target web page: my.hosting.nl/soap/server.php SOAP server IP address: Source port: 0 (never set to 80, causes it web server collision) Destination port: 80 (http servers usually listens at this port) Sending interval: 10 23

24 9. What to do when I forgot the IP address of the device Finding the device IP address IP address is set to the value by the manufacturer. If you changed it and forgot the new IP address, run the TSensor program and press the Find button. In a new window all sensors will be show. It is not possible to connect to the device from a LAN In the Find device window is only IP and MAC address displayed The next information is displayed as N/A. This problem will be occurred, when the device IP is set to another LAN. In TSensor program choose Find device/change IP address. Follow the program instruction. The sensor IP address in Find device window is not displayed In TSensor program select Find device/help my device Wasn t found! Follow the program instruction. Finding the MAC address The MAC address is a unique address of a device which is necessary to be known e.g. in case when there are several devices connected to the network. MAC address is on device label. It is not possible to find meter after manual MAC enter In TSensor program select Find device/help my device Wasn t found. In this select Set IP to ARP only. Into device MAC address enter the meters MAC address (e.g A-84-F0-80) and press the Set IP button. Open telnet to the IP address you assigned to the device MAC address by running a telnet command telnet [IP_address_assigned_to_MAC_address] 9999 and confirm with the Enter key. Choose 0 - Global Settings, set the meters IP address, clear the gate IP, no. of net mask set to 0. Pres the Enter key, until you are not back into a menu. Press - 9 Save and Exit. The connection will be closed. Now you can connect to meter by the TSensor program. LCD display is Off check if power supply is connected properly disconnect and connect the power supply - watch the display at the moment of connecting the power. If all LCD segments light for 1 second and go out again, the display is turned off by the software 24

25 10. Error States of the device Device continuously checks its state during operation. In case error is found LCD displays corresponding error code: Error 0 - first line of LCD displays Err0. Check sum error of stored setting inside device s memory. This error appears if incorrect writing procedure to device s memory occurred or if damage of calibration data appeared. At this state device does not measure and calculate values. It is a serious error, contact distributor of the device to fix. Error 1 - measured or calculated value (except concentration of CO 2 ) is over upper limit of allowed full scale range. There is a reading Err1 on LCD display. Value read from the device is This state appears in case of: Measured temperature is higher than approximately 600 C (i.e. high non-measurable resistance of temperature sensor, probably opened circuit). Relative humidity is higher than 100%, i.e. damaged humidity sensor, or humidity calculation of humidity is not possible (due to error during temperature measurement). Computed value calculation of the value is not possible (error during measurement of temperature or relative humidity or value is over range). The value of CO 2 concentration 9999 ppm is correct value! Error 2 - there is a reading Err2 on LCD display. Measured or calculated value is below lower limit of allowed full scale range or CO 2 concentration measurement error occurred. Value read from the device is This state appears in case of: Measured temperature is lower than approximately -210 C (i.e. low resistance of temperature sensor, probably short circuit). Relative humidity is lower than 0%, i.e. damaged sensor for measurement of relative humidity, or calculation of humidity is not possible (due to error during temperature measurement). Measured value of CO2 concentration is outside the range 0 to 2000 (10000) ppm Computed value calculation of computed value is not possible (error during measurement of temperature or relative humidity). Error 3 - there is a reading Err3 on LCD display upper line. Error of internal A/D converter appeared (converter does not respond, probably damage of A/D converter). At this state device does not measure temperature and relative humidity and computed values are not calculated. This error does not affect CO 2 concentration measurement. It is a serious error, contact distributor of the device. Error 4 - there is a reading Err4 on LCD display. It is internal device error during CO 2 concentration sensor initialization. Under this condition device does not measure concentration of CO 2. Value read from device is (concentration of CO 2 ). CO 2 sensor is probably damaged. It is a serious error, contact distributor of the device. Error 5, 6 - there is problem with assigned value to output relay, there is some wrong setting (mismatch). This error appears if incorrect writing procedure to device s memory occurred. Error 9 - inserted password is not valid, there is shown for short time message Err9 on LCD display. 25
